The TCS Toronto Waterfront Marathon is Canada's largest marathon weekend, held in downtown Toronto in mid-October, with the marathon and half marathon on the third Sunday of the month and a 5K on the Saturday before. The marathon and half marathon start together at 8:00 a.m. on Yonge Street, just north of Gerrard Street, and the 5K starts at 9:00 a.m. on Bay Street near Front Street. All three races finish on Bay Street just north of Queen Street, beside Nathan Phillips Square, which serves as Race Central. The marathon route takes in the downtown core and long stretches of Lake Shore Boulevard along the waterfront. Field caps are 9,500 for the marathon, 13,000 for the half and 8,500 for the 5K, and the 2026 edition sold out at every distance. Marathoners have six hours to finish and half marathoners three and a half hours. Aid stations sit roughly every 3 km. Every finisher receives a medal and an ASICS souvenir shirt. The race doubles as the Canadian marathon championships and draws an international elite field. Ethiopia's Waganesh Mekasha holds the women's course record of 2:20:44, set in 2024. Registration is on Race Roster, and the organiser lists partner hotels downtown with race-weekend rates.
